A spring is arranged between the arc guide rod 71 and the arc pipe 7, when one side of the arc plate 72 is contacted with a wall body, the arc plate 72 can not move under the action of external force, and the situation that the arc plate 72 is damaged is avoided.

The end of the arc-shaped plate 72 away from the arc-shaped guide rod 71 is provided with a rubber layer 8. The rubber layer 8 prevents the arc-shaped plate 72 from directly contacting with the wall body, and the service life of the arc-shaped plate 72 is further prolonged.

The fixing component 2 further comprises a driving component 3, and the driving component 3 drives the arc-shaped pressing plate 25 to partially move to the outer side of the first shell 1 and contact with one side of the wall body. Cross arc clamp plate 25 and baffle 11 and all contact with the wall body of prefabricated hole department, and then fix whole distribution switch in prefabricated downthehole, and arc clamp plate 25 makes it the motion through drive assembly 3, makes things convenient for operating personnel to carry out the dismouting, has improved work efficiency, also avoids simultaneously carrying out the drilling operation to the wall body.

The driving assembly 3 comprises a second fixing rod 31, one end of the second fixing rod 31 is fixed at the bottom of the inner wall of the second casing 21, and a worm 32 is rotatably arranged on the outer peripheral surface of the second fixing rod 31. The bottom of the rotating block 24 is provided with a worm wheel 33, the worm wheel 33 is rotatably sleeved on the first fixing rod 23, and the worm 32 is meshed with the worm wheel 33; one side of the worm 32 far away from the second fixing rod 31 is provided with a driving component 4, and the driving component 4 drives the worm 32 to rotate.

The worm 32 is connected with the second fixing rod 31 in a damping rotation mode. The relative position of the worm 32 and the second fixing rod 31 is difficult to change without being affected by external force.

Before the power distribution switch is installed, the arc-shaped pressing plate 25 is integrally located inside the first through hole 22 and the second housing 21. The arc-shaped pressing plate 25 is not partially positioned outside the first shell 1, so that an operator can conveniently plug most of the first shell 1 into the prefabricated hole.

The driving assembly 4 includes a rotating rod 41, and the rotating rod 41 is disposed through the second housing 21. The knob 5 is fixed to one end of the rotating lever 41 outside the second housing 21. Knob 5 facilitates rapid rotation of rotating lever 41 by an operator.

The top of worm 32 evenly is provided with a plurality of guide arms 42 along its border direction, and a plurality of first standing grooves 43 have evenly been seted up along its border direction in the bottom of dwang 41, and the even first standing groove 43 quantity in guide arm 42 quantity and position are corresponding, and the one end of guide arm 42 extends to inside corresponding first standing groove 43, and is provided with first spring 44 between guide arm 42 and the corresponding first standing groove 43, and the both ends of first spring 44 are fixed mutually with the one end of guide arm 42 and first standing groove 43 inner wall one side respectively. A rectangular block 45 is fixed on the top of the worm 32, a second placing groove 46 is formed in the bottom of the rotating rod 41, and the shape of the second placing groove 46 is matched with the shape of the rectangular block 45. When the first spring 44 is in a natural state, the rectangular block 45 is out of contact with the second placement groove 46. Through rectangular block 45 and second standing groove 46, when rectangular block 45 was located inside second standing groove 46, operating personnel can rotate worm 32 through dwang 41, when dwang 41 did not receive the exogenic action, under the effect of first spring 44, rectangular block 45 and second standing groove 46 break away from the contact, only lean on the contact force between guide arm 42 and the first standing groove 43, when touching dwang 41 unintentionally, can not drive worm 32 and rotate.

The outer peripheral surface of the rotating rod 41 is provided with a limiting plate 6, the limiting plate 6 is located inside the second housing 21, and when the first spring 44 is in a natural state, the top of the limiting plate 6 is in contact with the top of the inner wall of the second housing 21. The limiting plate 6 limits the moving distance of the rotating rod 41 on the second housing 21, and simultaneously ensures that the guide rod 42 and the first placing groove 43 are always in a contact state, thereby ensuring that the rectangular block 45 quickly enters the second placing groove 46 when the rotating rod 41 is pressed.

The implementation principle of the above embodiment is as follows:

the operator first plugs the first housing 1 mostly inside the preformed hole. And the first housing 1 is well positioned.

Next, the operator turns the knob 5 inside the first housing 1, and may turn the knob 5 in sequence, or may turn the knob 5 in a diagonal line.

The operator first presses the knob 5, and the knob 5 drives the rotating rod 41 to move downward, so that the first spring 44 is compressed and deformed, and along with the movement of the rotating rod 41, the rectangular block 45 is located inside the second placing groove 46. In this case, the operator keeps the current position of the rotating lever 41 unchanged. An operator rotates the knob 5, the knob 5 drives the rectangular block 45 to move, and the rectangular block 45 drives the worm 32 to rotate. The worm 32 rotates the worm wheel 33. The worm wheel 33 drives the rotating block 24 to move, and the rotating block 24 drives the arc-shaped pipe 7 to move.

The arced tube 7 drives the arced plate 72 to move, and finally, one end of the arced plate 72 contacts the wall.

At the moment when the arc plate 72 contacts the wall, the operator will not stop rotating the knob 5, and the knob 5 will continue to drive the rotating rod 41 to rotate, so that the arc tube 7 will continue to move. Since the position of the arc plate 72 does not change, the length of the arc guide rod 71 inside the arc tube 7 changes, and the second spring 73 is in a compression deformation state.

Due to the damped rotational connection between the second fixing rod 31 and the worm 32. The elastic restoring force of the second spring 73 cannot be the reverse rotation of the worm 32.

Finally, the operator releases the knob 5, and the rectangular block 45 is out of contact with the second placement groove 46 by the elastic restoring force of the first spring 44. The contact area between the rotating rod 41 and the worm 32 is reduced, when the knob 5 is touched by accident, the force applied to the knob 5 is not large, and in addition, the worm 32 is in damping rotation connection with the second fixing rod 31, so the worm 32 cannot rotate, and the installation position of the distribution switch is kept unchanged.

The operator sequentially brings one end of each of the arc plates 72 into contact with the wall according to the above-described operation method.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
